For example, I will go to http://www.random.org and I will generate a sequence of numbers in 2 columns. These numbers will correspond to the team numbers. The odd man out will have a bye week. In week 3 Danryan and hornet95 received the bye.
I just ran this sequence:
10 15
11 12
7 5
4 3
9 2
6 1
13 14
8
8 would have got the bye week if there were 15 teams remaining and this sequence came up.
